Major league teams annually wear green caps for St. Patrick’s Day spring training games, but the Baseball United Foundation has an even better way for the game to embrace Irish heritage. The New York-based foundation is trying to grow baseball in Ireland. As BUF founder John Fitzgerald says: “There are these guys in Ireland actually playing baseball, not just wearing a green T-shirt.”

So if buying a green Giants, Red Sox or White Sox cap doesn’t quite cut it for your St. Patrick’s Day interest, you can go to BaseballUnitedFoundation.org to purchase actual Irish baseball merchandise. Or make a small donation — as part of a spring campaign, Fitzgerald is asking for contributions as low as $1 to $10.
